Title: Stepwise deep burning by constructing underground vaults - for further coaxial drilling enables increase of max. boring depth for mineral and other exploitation
Inventor: BLAUER MIKLOS ZOLTAN
IPC: E21B43/30
Filed: 1988-07-29
Abstract: This is a deep-boring method for the exploitation of mineral resources and geothermal energy at depths not normally possible. A deeper working depth is reached in stages. If, after exploitation by normal methods, a greater depth is needed for further work at least two parallel boreholes of large dia. (D) are sunk as shown in the diagram, and lined with the usual type of steel casing, down to an economic depth. At this depth, a vault is made to serve as a new level to start further boring by personnel and equipment (including power supply) lowered through the first boreholes. Further boreholes are sunk coaxially with the first ones, for constructing the next vault. At least two parallel boreholes are made, for ventilation. Further vaults are made in a similar way, down to a planned depth. In the diagram, derricks (Bohrturme) and boreholes (Bohrungen) are indicated. USE/ADVANTAGE - Max. boring depth is normally limited by the strength of the steel casing. The proposed technique enables max. boring depth to be increased to allow deeper exploitation.

Title: Elastic sealing ring for a plug-in connection designed as a sliding ring seal
Inventor: MUECHER HORST ADOLF
IPC: E03F3/04
Filed: 1988-12-08
Abstract: In order to protect a sealing ring (2), intended for producing a plug-in connection of pipes, against the attack of aggressive media, e.g. against chlorinated or aromatic hydrocarbons, said ring exhibits, on the sub-region of the outer casing of its elastic core ring (1) which is exposed to the attack by media, a protective coating (3) which is resistant to aggressive media, e.g. consisting of PTFE. In place of a connection, produced by complex and costly adhesive bonding or vulcanisation, between the elastic cone ring (1) and the protective coating (3), said protective coating (3) has, according to the invention, at least one axially arresting retaining part (9) which effects and ensures the connection, in a manner which is reliable in terms of mounting and permanent functioning, between these two parts of the sealing ring (2). A sealing ring (2) which is resistant to aggressive media and can be simply fabricated in this manner also protects in the long term - in conjunction with the pipe material suitable for this purpose, e.g. stoneware pipes - the groundwater supplies, which are essential for drinking-water supply, from contamination by hazardous toxic substances, for example by chlorinated hydrocarbons, aromatic hydrocarbons, dioxins or the like. <IMAGE>

IPC: D21G1/00
Filed: 1989-06-21
Abstract: The smoothing takes place in a smoothing zone (2), in which the operation is carried out under pressure using temperature and moisture. The desired smoothness is achieved with a correspondingly long residence time of the web of material (1) in a smoothing zone (2) which is correspondingly long having regard to the velocity of the web. A still moist web (1) is guided between heatable surfaces (3, 4) which are arranged on both sides of the web (1), face each other across the web, extend in parallel and can each be pressed against the web. The surfaces (3, 4) are constructed over their entire length for forming and holding a given, defined contour of smoothing zone (2). The one surface (3) is, for example, constructed as an outer surface (5) of a heated cylinder (6) and the second surface (4) is constructed as a continuous flexible belt (7) which can be pressed towards the outer surface (5) of the cylinder by means of a concave support element (8).

Inventor: MUELLER JUERGEN
IPC: F16K21/14
Filed: 1989-06-28
Abstract: An automatic reversing faucet for a water pipe fitting for a bath/shower has an insert which can be screwed into the fitting. A guide rod with a closure element at one end and a knob at the other can slide axially in the insert against the force of a spring one end of which abuts on the closure element of the guide rod and the other end of which abuts on the insert. In its first position, the closure element causes water to flow into the bath and can be moved against the force of the spring by means of the knob into a second position which causes the water to flow from the shower. The closure element is returned to the bath-filling position when the hydrostatic pressure acting on the closure element is less than the pressure of the spring. The knob can be arrested in the shower position. For ease of manufacture and operation, the interior (24) of the socket-shaped knob (12) fits over a pin (23) mounted on the insert (15) and can slide freely on the pin, and clamping means (25) actuated by adherence in the shower position of the knob (12) are arranged between the wall (32) of the knob (12) and the pin (23).

Title: Replacement of a damaged bath tub - by a procedure specified in detail
IPC: A47K3/00
Filed: 1989-09-20
Abstract: Bath tubs of sheet metal or cast iron with an inside enamel coat are replaced by one of the same material or of plastics, when the enamel has been scratched or worn, by cutting up the old tub and removing the fragments.  The top end of the tile covered front support wall is chiselled off partly on the inside to permit the new tub to be inserted instead. To replace a bath tub (1) with a damaged enamel coat (12), the old tub is cut up sideways and removed. The inside of the front wall (5) with the tiles (9) is chiselled down enough on top to permit the new tub to be slid in and pushed in the slot (4). All joints are caulked with mortar or silicone cpd. ADVANTAGE - A min. of labour is required and leaves the tiled facing unharmed. The replacement tub is of the same size and need not be reduced in size.

Filed: 1990-05-14
Abstract: In this method, a frame is subdivided into moving and non-moving areas with the aid of the calculation of differences in the brightnesses in the successive frames. Displacement examinations are only carried out in areas for which movement has been found. In this arrangement, the examination starts from points which are located along an edge between a moving and a non-moving area. Since thus calculations are only carried out starting with relatively few points, the computing time can be enormously shortened in comparison with conventional methods. <IMAGE>
